Beckhoff PS9xxx buffer and redundancy modules increase system availability.
Beckhoff has expanded its universal 24/48VDC power supply series with the addition of its PS9xxx buffer and redundancy modules. The PS90xx buffer modules prevent disturbances caused by voltage dips and fluctuations by storing energy via maintenance-free electrolytic capacitors and releasing it as required. Require no control wiring, the buffer modules can be added in parallel to the load circuit at any point. The redundancy modules allow two or more power supply units, connected in parallel, to be decoupled by one or more redundancy modules. The redundancy modules use MOSFET technology for decoupling, which reduces voltage drops and power dissipation. Accordingly, the devices have lower power loss compared to conventional diode modules.
